Submillimeter polarization observation of the protoplanetary disk around HD 142527
Akimasa Kataoka, Takashi Tsukagoshi, Munetake Momose +8
We present the polarization observations toward the circumstellar disk around HD 142527 by using Atacama Large Millimeter/submillimeter Array (ALMA) at the frequency of 343 GHz. Th…
Radial decoupling of small and large dust grains in the transitional disk RX J1615.3-3255
Robin Kooistra, Inga Kamp, Misato Fukagawa +56
We present H-band (1.6 μm) scattered light observations of the transitional disk RX J1615.3-3255, located in the ~1 Myr old Lupus association. From a polarized intensity image, tak…
The intrinsic abundance ratio and X-factor of CO isotopologues in L1551 shielded from FUV photodissociation
Sheng-Jun Lin, Yoshito Shimajiri, Chihomi Hara +10
L1551 is chosen because it is relatively isolated in the Taurus molecular cloud shielded from FUV photons, providing an ideal environment for studying the target properties. Our ob…
A Gap with a Deficit of Large Grains in the protoplanetary disk around TW Hya
Takashi Tsukagoshi, Hideko Nomura, Takayuki Muto +7
We report 3 au resolution imaging observations of the protoplanetary disk around TW Hya at 145 and 233 GHz with the Atacama Large Millimeter/Submillimeter Array. Our observat…
Mass constraint for a planet in a protoplanetary disk from the gap width
Kazuhiro D. Kanagawa, Takayuki Muto, Hidekazu Tanaka +4
A giant planet creates a gap in a protoplanetary disk, which might explain the observed gaps in protoplanetary disks. The width and depth of the gaps depend on the planet mass and…
